------------------------------------------------------------------------------- |-- Module : Distribution.Simple.Build-- Copyright : Isaac Jones 2003-2005,-- Ross Paterson 2006,-- Duncan Coutts 2007-2008---- Maintainer : cabal-devel@haskell.org-- Portability : portable---- This is the entry point to actually building the modules in a package. It-- doesn't actually do much itself, most of the work is delegated to-- compiler-specific actions. It does do some non-compiler specific bits like-- running pre-processors.---- There's some stuff to do with generating @makefiles@ which is a well hidden-- feature that's used to build libraries inside the GHC build system but which-- we'd like to kill off and replace with something better (doing our own-- dependency analysis properly).--{- Copyright (c) 2003-2005, Isaac Jones
